What is ibogaine and how does it work?
mechanisms are not outcomesIbogaine is a psychoactive indole alkaloid derived from the root bark of the Tabernanthe iboga plant, native to West Africa. It is primarily known in discussions of detoxification and substance use disorder, not as an established therapy for amyotrophic lateral sclerosis.
Its pharmacology is unusually broad. Ibogaine can modulate neurotransmitters including serotonin and dopamine, influence NMDA-related signaling, and act on sigma-2 receptors. These neurological effects involve multiple parts of the central nervous system, which is one reason simple claims about a single mechanism are unreliable.
Its active metabolite, noribogaine, has a longer half-life that may extend up to 36 hours and is thought to contribute to prolonged effects. For a focused explanation of timing and metabolism, the discussion of noribogaine’s longer half-life is useful context, but pharmacokinetics alone cannot show benefit for ALS.
The compound’s psychoactive properties and complex receptor binding also shape its risks. A broader background on ibogaine’s pharmacology and legal history helps place current attention in context.
